through the cylinders of the motor and its supporting base or bracket,

F 3 is a side view showing the valve chamber and valves in vertical section,

Fig. *1 a vertical transverse sectional view on line 1 4- Fig. 2, and

Fig. 5 is a detail view of the chambered cylinder head.

The motor is illustrated in the accompanying drawings as supported upon a bracket comprising a base 1 having a shoulder 2 adapted to engage a suitable vertical support 3 and a member l extending in parallelism therewith having a thumb or hand screw 5 passing through it provided at its end with a block 6 adapted to clamp upon the opposite side of the support 3. The base 1 is provided with upwardly extending integral bosses 7 and 8 which are cored out to form alined cylindrical apertures 9 and 10 adapted to receive the motor cylinder 11 and 12. The cylinders 11 and 12 may be formed of suitable tube material smoothly bored to receive the pistons. These cylinders may be and preferably are removably secured in the bosses and are provided with chambered heads 13 and let which may be in the form of hollow castings havin flanges 15 and 16 embracing the remote ends of the cylinders, screwed, welded or sweated upon them.

The piston heads may be formed in any desirable manner. As shown herein they preferably each comprise cylindrical members 17 and 18 inclosing a packing or ring 19 which may be made of fibrous material and are clamped together by bolts 20. The pistons desirably are secured together by rods 21 preferably three in number spaced one hundred and twenty degrees apart. A link 22 which may be connected to one of said cylinder heads is connected at its opposite end to a memher 23 01' a power actuating lever the end of which is bifurcated and provided with pivot screws 25, 26 which engage sockets in an overhanging bracket 28 which desirably is formed integral with the boss 7 on the base 1.

Jluid under pressure is supplied to the cylinders through a valve chamber which for convenience in manufacture and assembling is formed of three members, an inner membcr providing a compartment having inlet and exhaust sections, the outer members communicating through suitable ports with said carried by sections and also with the hollow heads 13, 14 ot' the cylinders. As illustrated herein the central member 29 of the valve chamber comprises a casting which has an extension or bracket secured to the base 1 and which is provided with an inlet port 3') and an outlet port 31. The outer members 82 and 33 are in the form ol' elongated chambers having at their upper ends extensions 34 and 35 which are respectively connected by pipes 36, 37 with lateral hollow extensions 39 and 40 upon the heads 14. and 13 respectively.

The members of the valve chamber may be and are connected by bolts 41 which serve to clamp the members of the casing together.

Partitions 42, 43, 44 and 45 are. interposed between the adjacent ends of the outer members of the valve casing and the inner member and these partitions are provided with ports leading from the inlet and outlet sections of the, inner member to theouter chambers. A valve 46 located in the inlet section of the inlet chamber is adapted to seat alternatively upon the ports 44 and 45 to control the iiow of iluid under pressure to the cylindersv 11 and 12. This valve desirably is alined rods 47. 48 which are con nected at their respective outer ends to levers 49 and 50 located in the outer chambers of the valve casing and pivotally mounted upon studs 51 and 52 extending across the walls of said chamber. The ports of the partitions 42 and 43 are alternatively opened and closed by valves and 54 carried by a link 55 which is pivotally connected at its ends to studs 56 and 57 in the ends of the levers 49 and 50, respectively.

The link 55 is provided intermediate of its end and within the exhaust chamber of the inner member of the valve casing with an aperture 58 which receives the end of an arm 59 carried upon a shaft 60 which is journaled in the wallsof an upward extension 61 oi the inner valve casing member. rrocker 62 which is secured to the shait 60 is adapted to be operated by the movement of the power transmitting lever 34 in such a manner as to reciprocate the link 55 and thereby alternately close the ports in the partitions 42, and 43 and simultaneously to cause the reverse operation ofthe valve 46 which controls the ports leading from the inlet section 01 the inner member of the valve casing.

Any suitable means may be provided for actuating the rocker 62. As disclosed herein the member lever is in the form of a fiat web 63 which has projectingfrom it a guide 64 having a central aperture 65. The rocker is provided at or adjacent its ends with rollers 66,67 which are mounted upon laterally projecting studs so that the rollers engage the guide 64. The guide 64 is in the form of an arc ting lever and the rocker 62.

23 of the power transmitting concentric with the center of the stud 25 about which the power transmitting lever operates. I 7

Means are provided for depressing alter: nately the ends of the rocker rollers 66 will alternately engage the underside of the guide 64. The preferred means illustrated in the accompanying drawing for accomplishing this purpose comprises a crank lever pivotally mounted upon a stud 68 upon the web 63 ot the power transmitits outer end with roller 70 which rests upon and rides over the upper surface of hell crank lever is connected to a helica spring 72 which is anchored at its opposite end in an eye bolt 7 23 passing throngh'a. lug 74 extending upwardly from and preferably integral with the web 63 ofthe power transmitting lever.

The power transmitting arm 24 may be connected to any suitable device which is to be reciprocated. As illustrated the outer end of the arm 24 is connected to the standard 75 of the dasher 76 of the washing machine having the standard 75 connected 1b}; a link 77 which extends in parallelism with the power transmitting member 24 and pivotally connected at its opposite end to a stud 78 upon the base/l;

In the operation of the machine fluid un-.

der pressure, such as water, introduced through the inlet port 30. flows through the inlet chamber 29. of the valve casing the pipe 36 and hollow head 14 into the cylin' der. hen this cylinder has been driven to the limit of its stroke as is illustrated in the accompanying drawings the roller 66 in the end otthe rocker arm 62 is brought directly above the aperture65in the guid 62 so that the The opposite arm 71 0 5 said bell having an arm 69 provided at 64 and is depressed through said-aperture by the Force of the spring 72 acting'through the bell crank lever arms 71 and 69 and roller 70. This rocks the arm 59 from the position illustrated in Fig. 3 so that the valve 46 closes and simultaneously therewith opens the port 'in the partition 45, thus establishing communication with the opposite cylinder ll.

At the same time the valve 54 is unseated fromthe port in the partition 42, thus pen mitting the fluid to exhaust from. the cylinder 14 through the chamber 32, the port in the partition 42 and the exhaust port 81 so that as the fluidunder pressure is supplied to cylinder 11 it will be simultaneously exhausted from the cylinder 12.

This will cause reciprocation oi the pistons in the opposite direction, raising the power transmitting lever 24. Inasmuch as the web 63 is carried by the lever 24 the guide 64 will move toward the left Fig. 2 until the aperture 65 comes beneath the roller 67 on the rocker 62. In the meantime the port in the partition 44.

1 the roller will havebeen carried over the upper surface of said rocker and will be in position to depress the roller 67 through the aperture 65 when the latter comes beneath said roller. This will shift the rocker 1n the Opposite direction, thus moving the arm 59 back to the position illustrated in Fig. 3 and thereby opening the exhaust port for the cylinder 11 in the partition &3 and simultaneously opening the supply port for the cylinder 12 in the partition aid.

The construction above described, it will be noted, is of a simple character which can easily and economically be constructed.

The base, cylinder holders, and overhanging arm 28 may be cast in one piece of relatively cheap material, The cylinders 11 and 12 may be made of high grade material and when sweated or otherwise secured within the cylinder holders will provide efficient and lasting cylinders for the machine. The cylinder heads can be readily constructed by casting and sweated upon the ends of the cylinder.

The piston construction is of an inexpensive character and when the parts thereof are assembled and connected together by the rods 21 a rigid piston structure is provided. The valve operating mechanism is simple in character and the valve chambers are so constructed that they can be readily removed and replaced.

By reason of this fact the partitions d2, l3, M and 45 which contain the ports between the inner and outer valve chambers, may be made of rubber or fibrous material and readily replaced by the user of the machine when they become worn without the necessity of returning the machine to the factory.

It will be understood that the embodiment of the invention disclosed herein is of an illustrative character and is not restrictive and that various changes in construction and parts may be made within the spirit and scope of the claims and that the motor forming the subject matter of my invention may be adapted for various uses.
